OK Honestly! What's the difference between "campaign contributions" and "bribes"?...?

There isn't much of a difference. That is how all these labor unions got all these lavish salary packages, retirement programs and benefits packages. It should be illegal for anyone to gain materially from campaign contributions. Same goes for the vacations and other material benefits from lobbyists to congressmen. If an executive with a private corporation received that type of renumeraiton from a supplier in order to influence decisions they would be fired.
